Be it known that I, Boson, a citizen of the United States, res ding atjMankato, in the county of Blue Earth and State of Minnesota, haveinvented certain new and useful Improvements in Motor- Vehicles; and Ido hereby declare the following to be a full, clear, and exact in theart-to which it appertains to. make and usethe same.

This invention relates to the (hi of motor vehicles; and it consists Inthe novel construction and combination of the 'Inthedrawmgs,'higurelisasidevien' of-portions ofa motor vehicleportionsofthemachineinsection. Fig.2isa crosssectiontakmonthelineHinFig. 1. Fig.3isatrontviewofthesteeringFig.4isaplanviewofthesame. Fig.5is a long "tudinal section through theend tion of one of the axles.

Aaretheside-barsofthefi'ameofthe vehicle which is of any approvedcmstruction, and B is any approved motor secured betveen the said fISagHIGSmg ormedo three so posedsectionsL-Qandl,flangesandsecuredtogetherbyboltso D are curved brackets of rmilientmaterial secured to the side-bars A and-to'the lower secti0n3 of thesaid The motor is operafively connected with a 1 driving-shaft 4 whichis journaled in bearings 5 formed atthe ends of the sections 1 and 2. Atoothed pinion 6 is secured on the shaft 4 insidethe casing.

E is a counter-shaft journaled in bearings 7 on the ends of the casections 2 and 3, and e is a toothed Wheel secured on the middiepart-ofthe shaftE andgearinginto the inion 6. The cas' is used as asupport or these wheels, and as a dust-proof oilchamber so that they maybe constantly lubricated and run'without perceptible noise.

F are similar axles at'the front and rear of the machine. These axlesare tubular, and they are supported from the frame of the vehicle ringsf. Each tubular axle has a similar fiving-shaft G journaled in it. Atthe middle part of each axle a casing His secured, and h is alongitudinal drivingshaft which projects from this A I compensating-gearI of any approved construction is inclosed in each IL and this gearoperatively the shaft h with the cross shaft. G, which is formed in twoin the usual manner,

J and K are two similar longitudinal driving-shafis provided at theirends with uni-.

g ar longitudinal shafts h of thecompensatinggealsLsothatthefmntandrearcmss driving shafts are driven vbracketsD permit thegearto oscillate to a limited extent; and

more in a direction longitudinal I' li f the frame, so that theuniversal couplings are not broken when the vehicle is traveling ,oyer-arough road andthe springs f are yielding.

The st eel-mg at each road wheel are all alike,and the description willtherefore be confined to one of them.

A forked bracket 10 is secured on the aid portion of the tubular axle F,and 11 is a circular chamber formed in the said bracket has an endportion g of smaller diameter than its main portion and which forms ashoulder 12. A small beveled toothed wheel 13 is secured on the endportion g. A conical roller race 14 is secured in the chamber A conicalhush 15 is secured on the end portion g of the shaft against theshoulder 12, and 16 are anti-friction rollers which run between the saidrace and bush, Washers 17 are secured between the bush 15 and the wheel13, and one of these washers closes the space between the race and bushso that the rollers cannot slip out, and so that dust is excluded fiomaccess to them.

The rollers 16 have their axes inclined towards the main part of theshaft G at the middle of the axle, so that they receive the end thrustas well as the vertical pressure.

A pin 18 is a vertically in the said forked bracket, an 19 is a sleevewhich is pivoted on the lower part of the said pin. This sleeve 19 isprovided vdth a projectin arm 20 for the attachment of a steering-1 21.A. bearing-s indle 22 also projects from the sleeve 19, an is arrangedbelow the axis of the shaft G.

A road-wheel L of any approved construccmoentricwiththeaxle.ThecrossshaftG.

tion is journaled on the spindle 22, and 24 is a beveled toothed wheelsecured to the hub 4 Wheel 25 is arranged in gear with the small wheel13, and the pinion 26 is arranged in gear with the beveled toothed Wheel24 on the road-Wheel.

The washers 1? permit the adjustment of the two small beveled toothedwheels, and the roller-bear'ng receives the thrust of the Wheel 13 andenables the parts to run very smoothly. The shaft G is arranged a littleabove the axis of the road-wheel spindle, so that a liberal space isprovided between the casing of the compensating-gear and the ground.

Braces 28 are provided below the axle between the casing ofthecompensating-gear and the forked bracket, to strengthen these parts andto prevent the middle portion of the axle from sagging.

What I claim is:

In a motor vehicle, the combination, with a frame, road-wheels journaledat each end of the said frame, and driving devices fJI the saidroad-wheels provided with longitudinal shafts h of a motor carried bythe said frame and provided with a motor-shaft, a gear-casing having oneend portion of the said motor-shaft journaled in it, spring-armssupporting the said gear-casing from the said frame independent of thesaid motor, a countershaft journaled in the said gearcasing, toothedwheels incldsed in the said casing and connecting the said motor-shaftand countershaft, longitudinal shafts J and K, and universal couplingsconnecting the ends of the shafts J and K with the ends of thecountersha'ft and with the longitudinal shafts h.

In testimony whereof I have afiixed my signature in the presence of twowitnesses. ERNST ROSENBERGER. Witnesses:
